During the hot summer months, many mosquitoes enter the loft and they spread many kinds of diseases. There is not much anyone can do about these pests, but they can be controlled to a great degree. An insect strip, changed every three weeks, will control most of the mosquitoes. Most strips are supposed to be effective for three months but when placed in the loft, which is really outdoors, they are effective for three weeks only.
